Well, the problem is that when I'm working on a project, I'm constantly tweaking the textures and testing them in poser. In fact, that's exactly what I was doing when this happened. So read-only isn't really an option for me. Hence the triple back-up. I'm fairly used to the rsr corruption when poser crashes. I just delete the culprit and carry on. But the really weird thing about this is that it happened when poser was open and there was no crash. This was just another render, after having done several, and it just went mad. I'll be finished this project in a week or so and I think I'll just re-install. No biggie. I'm so used to it now. All I do is re-install, delete the entire runtime, then drag my current project files from the other drive, complete with prefs, custom .ini file, etc. mac
